PEEK makes oil & gas breakthrough

• PEEK material meets most severe sour gas single-phase environment conditions at high H2S levels
• Quadrant is first in the industry aligned to ISO 23936-2:2011 requirements
• Material suitable for hostile HPHT environments up to 200 °C

Quadrant Engineering Plastic Products has achieved NORSOK M-710 compliance for its Ketron 1000 PEEK (natural) extruded stock shapes (plates, rods and tubes). Samples machined from the shapes performed successfully when exposed to 10% hydrogen sulphide (H2S) in 100% gas phase, as described in the ISO 23936-2:2011 standard.

The new compliance qualifies not only the resin, but also the process and machinery used by Quadrant in its conversion of polyetheretherketone (PEEK) into semi-finished products, offering the highest compliance ranking of the supply chain to the market. It follows last year’s achievement of NORSOK M-710 multiphase compliance for Quadrant’s Ketron 1000 PEEK. It is a major accomplishment as the industry prepares for future ISO 23936-1 standards.

Material resistant to 10% H2S sour gas at up to 200°C

All tested materials passed the various NORSOK M-710 criteria, which cover aspects such as swell, Young’s Modulus and visual inspection. Based on these results, the qualifying institute, ‘Element Materials Technology,’ was able to certify that Quadrant’s Ketron 1000 PEEK extruded plate, rod and tube are resistant to 10% H2S sour gas at temperatures up to 200°C.

For the oil and gas production industry, the company supplies its Ketron 1000 PEEK natural stock shapes (produced via extrusion, injection- and compression molding techniques) for numerous applications, including well completion, control systems, downhole tools and valves.

What are NORSOK standards & ISO 23936?

The NORSOK standards were developed by the Norwegian petroleum industry to ensure safety, add value, and improve cost effectiveness of the industry’s developments and operations. Standard M-710 defines requirements for critical non-metallic sealing, seat and backup materials for permanent use subsea. The standard also applies to topside valves in critical gas systems.
The ISO 23936 (petroleum and natural gas industries – non-metallic materials in contact with media related to oil and gas production) standards are issued by the International Organization for Standardization. They are separated into several sections: ISO 23936-1 (Thermoplastics), -2 (Elastomers), -3 (Thermosets) -4 (Fibre reinforced composites) and -5 (Other materials).
